If the charging current is equal to the reference table value then insert the normal battery
and test the charging current to verify that the phone battery is working properly.
Measure the voltage at the battery to define the current level.
If the battery is receiving the right current, then the phone and the battery are working
properly.

Note: The upper table contains the absolute limits for the readouts. The lower table
contains the allowed delta between the first and the second readout, separated in
time with 30 seconds.
If the readings are out of limits replace C2214 Backup capacitor.
If the problem is not solved then SL 5 Replace N2000 SL 4 Escalate.

Charger Control

Resistance Identification and Temperature Measurement

A programmable charger is used for battery charging. Limits can be set for the output
voltage at CHSENSE- and the output current from DCIO through the sense resistor to
CHSENSE-. The programmable charger is enabled or disabled by the assertion/negation
of the external signal DCIO. Parts of the programmable charger are activated and
deactivated depending on the level of VBAT. The rest of the programmable charger is
activated and deactivated through I2C.

The resistance identification mode utilizes the constant current source to feed the
battery data output while monitoring the voltage at the battery data node with general
purpose ADC the conversion is started through I2C.
Resistance Identification (A) and Temperature Measurement (B):

The programmable charger supports the following functions:
•
•
•
•
•
•
•
•
•

Constant current charging
Constant voltage charging
Trickle charging
PWM controlled charging
Over-voltage and over current detection
Watchdog termination
DCIO assertion/removal detection
Voltage and current measure functions
Low resistive path (reverse mode)

SIM Interface
The SIM interface supplies level is shifting between the digital baseband controller and
the SIM/USIM card. Moreover, hard-wired SIM deactivation functionality manages
removal of a SIM card that has not been powered down.
Block Diagram of the SIM Interface:

FUNCTIONAL OVERVIEW

The programmable charger is able to control the voltage and limit the current to a load
seen at CHSENSE-. The programmable charger can also be run in PWM mode to turn the
charging on and off in accordance with the particular period and duty cycle. When the
charging is on, it is set to the current and voltage selected by I2C.
A low resistive path from VBAT to DCIO can be formed when DCIO is not detected.
When this setting is done in the appropriate registers, a lowering of CHREG to 0 V turns
on the external pass device. The pass device is automatically turned off when an
external source is detected on DCIO, or when the watchdog termination block times out.
The watchdog termination block must be active when the external switch is enabled,
both in normal
charging mode and in the low resistive path mode. The watchdog is set through the
serial interface, and if it has not been set again before timeout, the watchdog turns off
the external switch. The watchdog is disregarded during trickle charging. When no
battery is present, the system can be booted and supplied from DCIO by
applying the correct voltage on DCIO.

USB Charger
The analog baseband controller contains a standalone USB charger.
The USB charger has a separate input and incorporates full functionality during low VBAT.
The programmable charger supports the following functions:
• Trickle charging
• Constant current charging
• Watchdog termination
• Trickle LED indication
• VBUS assertion/removal detection

CODEC Overview

CODEC CCO Voltage Source

The CODEC is encoding analog audio signals and analog voice signals into digital signals
using Analog to Digital converters (ADCs). This is done in the coder section of the
CODEC, also named the TX path (transfer section). The CODEC is also decoding digital
audio signals and digital voice signals into analog signals using DACs. This is done in the
decoder section of the CODEC, also named the RX path (receiver section).

There is an internal voltage source CCO that provides the necessary drive current for
electret microphones. The voltage source is I²C programmable to 2.2 V or 2.4 V. The
source can be disabled during standby. A typical use case with a microphone connected
to MIC1 and the CCO is shown in picture below.

CODEC Block Schematic:

FUNCTIONAL OVERVIEW

Earphone Amplifier
The earphone amplifiers (BEARP and BEARN) are mainly intended to be differentially
configured and drive a low impedance dynamic transducer (earpiece) but they can also
be single ended configured. The BEARP and BEARN amplifiers can be powered down by
the I2C. The amplifiers can exhibit high impedance to 1.4V or low impedance to ground
when powered-down. Fifty-one gains are available for BEARP and BEARN: from +15dB
down to –60dB in 1.5dB steps. When the BEARP and BEARN outputs are operating in
differential mode, an I²C selectable bit must invert one of the inputs.

Speaker Amplifier
The speaker amplifiers, SPKRP and SPKRN, are intended to drive a low impedance (8Ω)
speaker in a differential mode or to be used as a stereo configured line output amplifier
supporting external high power amplifiers. The output buffer shall exhibit low impedance
to ground when powered-down and the current consumption shall be minimal. When the
SPKRP and SPKRN outputs are operating in differential mode, an I²C selectable bit must
invert one of the inputs.

FUNCTIONAL OVERVIEW

Digital Baseband Controller (CPU)
N2010 (Kajsa)
This component is not replaceable on SL 4 because Baseband calibration is required.
The Digital Baseband Controller is divided in two subsystems: Access and Application

Access Subsystem
All modem functionality in the digital baseband controller resides in the Access
subsystem. This includes EDGE/GPRS/GSM interface, WCDMA interface, USB, IrDA, and
other peripheral modules. The control CPU is an ARM926 and a DSP is used for signal
processing and layer one control code.
The main communication between the blocks in the Access subsystem is done through
the Advanced High-performance Bus (AHB) matrix, which is a set of control buses
connecting the different parts together. A block called Syscon is responsible for
distributing clocks and resets to all parts of the Access subsystem. This block is under
SW control. The Access subsystem is connected to the Shared EMIF, an interface for
communication with an external SDRAM. The Shared EMIF is shared between the Access
subsystem and the Application subsystem.

Technical Description

SEMC Troubleshooting Manual
C905

Application Subsystem
The Application subsystem contains functionality related to functions such as MMI,
graphics, audio and memory media. The control CPU is an ARM926 with three external
memory interfaces, one shared with the Access subsystem and two dedicated for the
Application subsystem. The Application subsystem contains several blocks. The main
communication between the blocks is done through the Advanced High performance bus
(AHB) matrix, which is a set of control buses connecting the different parts. A block
called Syscon is responsible for distributing clocks and resets to all parts of the
Application subsystem. This block is under SW control. The Application subsystem is

Radio Part
Antenna
The mobile system antenna interface connects the Wideband Code Division Multiple
Access (WCDMA) and Global System for Mobile Communication (GSM) input/output to
the antenna of the Mobile Phone. It is a bi-directional RF interface containing signals in
the range 800 MHz to 2.2 GHz. The mobile system antenna interface is the interface
between the Mobile Phone Radio Frequency (RF) input/output and the mobile system
antenna. The interface handles the GSM 850, EGSM 900, GSM 1800, GSM 1900 and
WCDMA Band I, II and V, RF inputs/outputs.
Mobile System Antenna Interface:

Radio Module N1200 (Tiger)
Front End

Keypad
The keypad interface block supports up to 30 keys with 65 columns and 6 rows and
operates in both scan and idle mode. The keypad scan is performed by software. Any
transition in the state of the column inputs is written directly to the register. The keypad
interface differentiates between single key presses, simultaneous presses of any keys
with a function key, and any key releases. The period between successive scans is
programmable over the range 5 ms to 80 ms, in 5 ms steps. During scan mode, the
keypad generates an interrupt whenever a valid keypad state change occurs (including a
release of any pressed keys). The scan function is disabled during system power-up. The
keypad is able to detect at least four simultaneous key presses. Not all combinations are
supported.

FUNCTIONAL OVERVIEW

The Front End block connects the proper block in the radio system to the antenna. The
Front End has two inputs for EDGE/GSM/GPRS, one for low band (850/900 MHz) and
one for high band (1800/1900 MHz). The EDGE/GSM/GPRS power amplifier output is
filtered by the low pass filter in the Front End and then connected to the antenna
through a switch. In receive mode, the EDGE/GSM/GPRS signal from the antenna passes
through the switch to one of the four receive SAW filters. The SAW filter provides receive
band selectivity. In GSM/GRPS/EDGE systems, transmit and receive operations are
divided in time and the switch connects the proper block in accordance with the mode of
operation (that is, transmit or receive; one at a time).
In WCDMA the transmit outputs from the WCDMA transceiver are filtered by an external
SAW filter that cleans up the spectrum. The SAW filter output is connected to the power
amplifier, one for each band. For power control, a sample of the transmit output is taken
by a directional coupler and converted to a DC level by the power detection circuit. This
signal is used to control the transmitter output power. The transmit signal passes
through an isolator and then a duplexer. The duplexer output is selected by the switch in
the Front End for connection to the antenna. In WCDMA receive mode the signal from
the antenna is switched by the Front End to the correct duplexer. The output from the
duplexer is connected to the LNA input in the WCDMA receiver.

Transceiver
The transceiver is a multi-mode transceiver for WCDMA/EGDE/GPRS/GSM. The
EDGE/GPRS/GSM part of the transceiver use a digital baseband interface that is shared
between received and transmitted data. The receive interface is based on I and Q data
and the transmitter interface is based on envelope and frequency data. The WCDMA part
of the transceiver use differential analog in-phase and quadrature-phase interfaces,
which is an IQ-interface, in the receiver and the transmitter data paths.

Frequency Generation

Technical Description

SEMC Troubleshooting Manual
C905

Ericsson RF 3300 Block Diagram:

The 26 MHz reference signal is used as the reference for the on-chip synthesizers. To
cover the required frequency range, the integrated Voltage Controlled Oscillator (VCO)
operates at twice the frequency for band 1800/1900/2100, and at four times the desired
frequency for band 800/900. The two synthesizers are controlled through the serial bus
from the access side of the digital baseband controller.

EDGE/GPRS/GSM Transmitter Part
Polar modulation transmitter architecture based on the direct phase/frequency
modulation/synthesizer architecture is implemented for GSM, GPRS and EDGE. This
architecture has the capability of generating both the GSM/GPRS constant envelope
GMSK modulation and the linear EDGE 8-PSK modulation in a very cost efficient way.
The motivation for a polar modulation transmitter architecture compared to traditionally
linear architectures is to reduce the output noise (thus eliminating the need for off-chip
filters) reduce the power consumption by utilizing non-linear switching analog signal
processing blocks, and to eliminate the need for an RF isolator.
In brief, the phase/frequency modulator in this polar modulation architecture is a sigmadelta controlled fractional-N frequency synthesizer with an additional frequency insertion
point after the loop filter at the input of the VCO. The Phase-locked Loop (PLL) has two
information inputs: the divider ratio in the feedback path and a direct path to the VCO.
The phase locked loop generates the radio frequency carrier including the phase
modulation information at the desired channel frequency.

WCDMA Transmitter Part

FUNCTIONAL OVERVIEW

The WCDMA transmitter architecture is an on frequency linear direct up-conversion IQmodulator. The in-phase and quadrature-phase reconstruction filters are fully integrated
and a programmable gain amplifier implements the gain control. An external SAW filter
between the WCDMA circuit and the power amplifier is used to improve noise
performance. After the power amplifier, the signal is sent through an isolator and
through the duplex filter, which directs the transmit signal to the antenna connector
through the antenna switch. The supply voltage and bias of the power amplifier are
adapted depending on the output power to achieve high efficiency at every transmitter
power level. A high efficiency DC/DC converter regulates the supply voltage and the bias
operation point is controlled by a D/A-converter in the WCDMA radio circuit.

Receiver Part
The receiver architecture is a direct down-conversion zero-IF receiver with integrated
low-pass filters. The complete receiver with seven Low Noise Amplifiers (LNAs), one for
each supported band, is integrated on chip. After the down-conversion, the in-phase and
quadrature-phase components are low pass filtered and if the receiver is in
EDGE/GPRS/GSM mode the signals are fed to the integrated high dynamic range sigmadelta A/D-converters.

RF System Control
The access side of the digital baseband controller controls the overall radio system.
In both EDGE/GSM/GPRS and WCDMA air interface mode, the digital baseband controller
controls the radio system through a three-wire serial bus. The digital baseband
controller also manages PA band control and the antenna switch mechanism in the front
end module. The 26 MHz VCXO clock residing in the transceiver is turned on only when
required and initiated by the digital baseband controller.

Bluetooth and FM Radio

External Connectors

The Bluetooth/FM Radio circuit combines Bluetooth and FM tuner functionality into one.

External units are connected to the transceiver by means of a 12-pin connector on the
bottom of the phone.

Bluetooth

System connector pin input/output overview:

The Bluetooth implementation is compliant with Bluetooth specification 2.1 + EDR.
The BluetoothTM transceiver has frequency channels with 1 MHz separation from 2402 to
2480 MHz. The same band is used for both transmission and reception. This gives 79
frequency channels.

Receiver
The Bluetooth section implements a low-IF receiver for Bluetooth modulated input
signals. The radio signal is taken from a balanced RF input and amplified by an LNA. The
mixers are driven by two quadrature LO signals, which are locally generated from a VCO
signal running at twice the frequency. The I and Q mixer output signals are band pass
filtered by a poly-phase filter for channel filtering and image rejection. The output of the
band pass filter is amplified by a VGA to the optimal input range for the A/D converter.
Further channel filtering is done in the digital part. The digital part demodulates the
GFSK, π/4-DQPSK or 8-DPSK coded bit stream by evaluating the phase information.
RSSI data is extracted. Overall automatic gain amplification in the receive path is
controlled digitally. The RC time constants for the analog filters are automatically
calibrated on chip.

Transmitter
The transmitter uses the serial transmit data from the Bluetooth Controller. The
transmitter modulator converts this data into GFSK, π/4-DQPSK or 8-DPSK modulated I
and Q digital signals for respectively 1, 2 and 3 Mbps transmission speed. These signals
are then converted to analog signals that are low pass filtered before up-conversion. The
carrier frequency drift is limited by a closed loop PLL.

FM Radio

The receiver uses a digital low-IF architecture. The receive (RX) section integrates a low
noise amplifier (LNA) supporting the worldwide FM broadcast band (76 to 108 MHz). An
automatic gain control (AGC) circuit controls the gain of the LNA to optimize sensitivity
and rejection of strong interferers. An image-reject mixer down converts the RF signal to
low-IF. The quadrature mixer output is amplified, filtered and digitized with high
resolution analog-to-digital converters (ADCs). This advanced architecture allows the
use of digital signal processing (DSP) to perform channel selection, FM demodulation
and stereo audio processing.

Tuning
The receiver uses frequency synthesizer technology including a completely integrated
VCO. The frequency synthesizer generates the quadrature local oscillator signal used to
downconvert the RF input to a low intermediate frequency. The VCO frequency is locked
to the reference clock and adjusted with an automatic frequency control (AFC) servo
loop during reception. The tuning frequency is defined as: Freq (MHz) = Spacing (kHz) ×
Channel + Bottom of Band (MHz)

Clock Distribution
The clocking for the access and application subsystems is separated. This means that
the subsystems can wake up or go to sleep mode independently. The access subsystem
is clocked by the 26 MHz Voltage Controlled Crystal Oscillator (VCXO) located in the
GSM/EDGE circuit. When the access subsystem has a job to do, the Master Clock (MCLK)
signal is requested from the RF part. Most other clocks needed within the access
subsystem are generated from the MCLK. Some minor parts like sleep timer and cable
detect use the 32 kHz real-time clock. The 32 kHz real-time clock clocks the application
subsystem, and all other internal clocks needed within the application subsystem are
generated from this clock. However, when audio is transferred between the application
and the access subsystems, the MCLK is used.

Master Clock
(26 MHz)
FUNCTIONAL OVERVIEW

FM Receiver

Clocks

The 26.00 MHz VCXO-based MCLK is distributed as a square wave signal from the
GSM/EDGE circuit. In order to have full control over the load on the MCLK, only the
access side of the digital baseband controller is allowed to request the MCLK. However,
by indirect means also the application side CPU can issue the request. A VCXO-based
square wave is also distributed to the WCDMA circuit, but is turned on only upon a
command from the digital baseband controller.

Real-time Clock
(32. 768 KHz)
A 32.768 kHz crystal oscillator provides a low frequency clock whenever the platform
has power. This clock is used to keep the Real-Time Clock (RTC) block functioning, so
that the platform can keep track of the time and date. The low frequency clock is
generated in the analog baseband controller and distributed to the digital baseband
controller, and if necessary to external devices like Bluetooth, FM radio and A-GPS.

FUNCTIONAL OVERVIEW

A-GPS

A-GPS Block Diagram:

The Assisted GPS functionality in the phone is realized with the Global Locate
Hammerhead GPS module. The Global Locate Hammerhead belongs to the Type 2 GPS
solutions. The PMB 2525 Hammerhead II GPS IC is a GPS single chip device containing a
complete radio frequency front-end as well as the signal processing functionality in a
single die. The device allows the usage of assistance data by supporting A-GPS (assisted
GPS) standards (RRLP, RRC, OMA SUPL). One of three serial interfaces, UART, I²C or SPI,
is used for communication with the host system.

Clock Reference Frequency
The platform provides two reference frequencies, a 32.768 kHz clock (RTCCLK) from the
Analog Baseband Controller, and a 26 MHz reference clock (SYSCLK) from the Digital
Baseband Controller. The RTCCLK is used by the phone real time clock function. The
RTCCLK is distributed to the A-GPS module as a logical square wave. SYSCLK is derived
from the reference modulation clock MCLK to the platform access system and is
distributed from the Digital Baseband Controller to the A-GPS module. This 26 MHz clock
is synchronized with the cellular network to an accuracy of ±0.1 ppm. Automatic
frequency updates can also cause large frequency corrections, with associated phase
discontinuities. In order to isolate the A-GPS module for the unstable effects of SYSCLK,
an external reference clock is required. This external reference frequency provided by a
TCXO is required to provide a clock with very high short term stability. The frequency of
the TCXO is calibrated against the cellular reference clock by the A-GPS module enabling
the use of a more economical less accurate TCXO.

Interface and Control
The Interface and control consists of system timing and control. The control interface
includes a communication link where both data and control information are transferred
between platform and the A-GPS module. Data and command information is transferred
using a full-duplex Universal Asynchronous Receiver Transmitter (UART) interface.

This WLAN module is based on the new Marvell 88W8686 chipset. WLAN module is
designed to support IEEE 802.11a or 802.11g payload data rates of 6, 9, 12, 18, 24, 36,
48 and 54 Mbps, as well as 802.11b data rates of 1, 2, 5.5 and 11 Mbps. For security
the WLAN module supports the IEEE 802.11i security standard through implementation
of the Advanced Encryption Standard (AES)/Counter Mode CBC-MAC Protocol (CCMP),
and Wired Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP) security
mechanism. For video, voice and multimedia applications the WLAN module supports
802.11e Quality of Service (QoS). The 3-wire Bluetooth / WiFi co-existence interface is
also supported. The WLAN module has a fully integrated RF to baseband transceiver that
operates in both the 2.4 GHz ISM radio band for 802.11g/b WLAN applications and 5
GHz UNII radio band for 802.11a WLAN applications. It contains all the circuitry to
support both transmit and receive operations. The integrated LNA and AGC on the
receive path is seamlessly controlled by baseband functions. Integrated transmitters upconvert the quadrature baseband signal and the deliver the RF signals to external power
amplifiers for 2.4 GHz and 5 GHz radio band transmission. Local oscillator frequencies
are generated by a fully integrated programmable frequency synthesizer. The loop
bandwith is optimized for phase noise and dynamic performance and quadrature signals
are generated on-chip.

FUNCTIONAL OVERVIEW

Other control signals include the following:
• A GPIO or platform reset used as a reset signal (nRESET) to the GPS module.
• A Transmission On signal (TXON/ RX_HOLD), is used to indicate to the A-GPS module
when the ME is transmitting. The A-GPS modules receiver is disabled whilst the ME is
transmitting.
• A hardware timing pulse (GPSSTART/SYNC) providing the A-GPS module with a
highly accurate timing reference. The A-GPS is able to accurately synchronize its
GPS time to this reference pulse.
• A GPIO used as an enable (POWERON) signal to the GPS module.
• A GPIO used for power control for the GPS module.

WLAN (Wi-Fi)

BT/WLAN Co-existence
Standards bodies did not fully anticipate the range of scenarios in which WLAN and
Bluetooth would compete for the same spectrum therefore IEEE 802.11 (WLAN) and
Bluetooth use the same 2.4 GHz ISM frequency band (although they use different access
mechanisms). They also did not include comprehensive, robust, and cooperative
mechanisms in their respective standards to mitigate interference. Since no mechanism
for exchanging signal status information has been built into the two standards, the task
of minimizing interference must be accomplished by other means. Co-location refers to
the situation where both Bluetooth and WLAN are in functional mode, that is, they are
both fully radio operational, performing either transmission or reception activities (or
ready to do so immediately). They also either share an antenna or each module has its

own antenna, on the same device. Because both Bluetooth and WLAN operate in the
same unlicensed ISM band (2.4GHz), steps are required to avoid disturbances and allow
coexistence. The HW solution is a single antenna controlled by an Antenna Switch with
3-wired lines between WLAN Device and BT Device. The used algorithm to decision
whether WLAN device or BT device gets the antenna is Packet Traffic Arbitration (PTA).
WLAN LD configures the PTA during startup of the WLAN device. All PTA parameters are
stored in GDFS. The PTA is configured to prioritize BT traffic if it is a BT high request. All
WLAN traffic should have priority before any BT traffic that is categorized as BT low
requests.
WLAN Driver sends status events to BT Driver to inform about:
• WLAN startup and shutdown
• WLAN association and disassociation
• The current WLAN channel in use
In the cases of WLAN startup and shutdown the BT Logical Driver configures the BT
Device to request the antenna from PTA or not. BT LD also monitors if WLAN have any
connection running. In that case, BT avoids the BT frequencies mapping to the WLAN
channel. WLAN monitors if BT has started any BT Inquiry or page. If this happens any
link loss mechanisms should be temporary turned off for the BT Inquiry or page period.

APPENDIX

Uses the default values in the TP to adjust the varactor diode to a pre-determined operating point, so
that the loop voltage of the TXVCO (measured with an ADC) is within the valid range and the optimal
value is chosen. The optimal value is defined as: The CVCO value that gives loop voltages within the
limits for both high and low channel and that has the lowest maximum loop voltage.

Note: Some parts of Audio and FM Radio may not be possible to implement for all products due to
limitations in ITP Software.

Mic1 is the internal microphone.
Aux1 is the input from the system connector.

Loop mode:
-

Analogue, where the loop is set before and after the AD/DA conversions.
Digital/DSP loop, where the DSP signal processing also affects to the audio signal.
CPU/PCM loop, where the loop is set between the PCM audio signals.
Dictaphone loop.
